🙋‍♀️ About Me

I am a third-year Ph.D. candidate in the School of Computing and Data Science (HKU-CDS) at the University of Hong Kong (HKU), advised by Prof. Reynold Cheng.

My research focuses on AI-native data systems and reusable intelligence for agent systems, including query processing over learned and structured relationships, graph hypothesis testing, and agent orchestration with memory retrieval.

I collaborate with Prof. Sihem Amer-Yahia (CNRS, France) and Prof. Laks V.S. Lakshmanan (UBC). I expect to graduate in August 2027. Feel free to reach out via email.
